It's pretty expensive to send stuff into space. As much as $43,180 per pound according to some estimates. Though SpaceX is hoping to get that figure down to around $9,100 per pound.

So just how much would it cost to send a fidget spinner to space? Based on that higher figure, and fidget spinners weighing about 16 grams, around $1,500. Which seems like a bargain.

That's probably why NASA decided to send astronauts on the International Space Station one of the hottest toys of 2017 as an early holiday gift. Adorned with the NASA logo, the video starts with NASA flight engineer Mark Vande Hei having some fun.

But it's not all about fun. There is some science being done.

A fidget spinner in space! How long does it spin? I'm not sure, but it’s a great way to experiment with Newton’s laws of motion! pic.twitter.com/5xIJDs2544
